The goal of the present correlational study is to test the hypothesis that anger initiates essential hypertension in Canadian Caucasian adults with a family history of hypertension. The study population will include a cohort of 100 men and women aged 25 to 45 years at enrollment recruited from the University of Ottawa General and Civic Hospitals. Participants who are normotensives will be included in the study given that they have a family history of hypertension. The Spielberger State Trait Anger Expression inventory (STAXI) scales will assess the three main dimensions of anger: State, Trait and Anger Expression. Using a semiautomated blood pressure machine, blood pressure measurements will be conducted by the attending nurse. It is hypothesized that during the three year study, participants with higher STAXI scores will more likely develop hypertension. Results obtained from the present study are expected to highlight the significant contribution of anger as a modifiable behavioral risk factor in the pathogenesis of hypertension.

1. Erythrocyte lithium—sodium counter-transport was measured in 46 normotensive healthy controls without family history of hypertension, 15 subjects with essential hypertension, but without evidence of family history of high blood pressure, and 43 subjects with essential hypertension and at least one hypertensive first-degree relative. 2. Mean values (mmol h−1 l−1 of erythrocytes) were 0.248 ± 0.092 in controls, 0.258 ± 0.087 in hypertensive subjects without family history (not significant vs controls), 0.360 ± 0.115 in hypertensive subjects with family history of hypertension (P < 0.001 vs controls), 0.334 ± 0.117 in all hypertensive subjects, both with and without family history (P < 0.001 vs controls). 3. Our data confirm the finding of an increased erythrocyte lithium-sodium counter-transport, but with a significant overlap between essential hypertension and control values. Lithium-sodium countertransport is higher only in hypertensive subjects with at least one hypertensive first-degree relative. 4. We suggest that the increase of lithium-sodium countertransport in erythrocytes is not a consistent marker of essential hypertension. It seems to be associated with the family prevalence and/or the hereditability of hypertension, rather than with high blood pressure per se.

1. The rate (k) of initial efflux of noradrenaline from platelets was determined in 63 individuals. A highly significant correlation was found between diastolic blood pressure and efflux rate. 2. When platelets are incubated in buffers with various Na+ concentrations in the range 110–170 mmol/l a higher Na+ concentration will give a faster efflux of noradrenaline for each concentration tested. 3. The value for k was determined in 41 normotensive first-degree relatives of hypertensive individuals and 21 persons with no family history of hypertension. Efflux rate of noradrenaline was significantly higher in the relatives and within this group was a subgroup with very high k values.

Aims: To identify the prevalence of hypertensions, socio demographic characteristics, risk factor and awareness of the study population about hypertension in Khartoum Locality. Study Design: A descriptive community-based cross-sectional study. Place of Study: Khartoum locality, Sudan. Methodology: A total of 587 adult participants were interviewed using structured close ended questionnaire. Blood pressure was measured considering hypertension as ≥ 140 mmHg and ≥ 90 mmHg for systole and diastole blood pressure respectively. Body Mass Index (BMI) was calculated and the cutoff points were derived from World Health Organization (WHO) reference criteria to classify BMI as normal, overweight and obese. Chi square test was used to assess the association of socio demographic characteristics and risk factors with hypertensive population. Results: The prevalence of hypertensive accounted to 216 (36.8%).  Thirty seven hypertensive participants (17%) were not aware about having hypertension, 86 (40%) were not aware about at least one complication of HTN and 117(54%) were not aware about the normal measures of blood pressure. The hypertensive participants were significantly high in the age group 25- 64 years of age and above. Females were significantly having hypertension more than males, 155 (72%) versus 61 (28%). Married participants were significantly having hypertension more than non-married, 169(78%) and 47(22%) respectively. Unemployed participants were significantly having hypertension more than employed ones, 168 (77.8%) and 48 (22.2%) respectively. Risk factors among hypertensive participants were significantly found among overweight 67 (31%) and obese 115 (53%), positive family history of hypertension 139 (65%), increase salt in food149 (69.3%) and physical inactivity 166 (77%). Conclusion: The prevalence of hypertension among Khartoum locality was high.  Hypertensive population awareness was low. Age, sex, marital status, education and employment were significantly associated with hypertensive population. Obesity and overweight, family history of hypertension, increase salt in food and physical inactivity were risk factors among hypertensive study population.

Erythrocyte Sodium

1. During 4 weeks 37 normotensive 50-year-old men identified by screening in a random population sample were given 12 g of NaCl daily, in addition to their usual dietary sodium intake. Blood pressure, heart rate, weight, urinary excretion of sodium, potassium and catecholamines, plasma aldosterone and noradrenaline and intra-erythrocyte sodium content were determined on normal and increased salt intake. The subjects were divided into those with a positive family history of hypertension (n = 11) and those without such a history (n = 26). 2. Systolic blood pressure and weight increased significantly irrespective of a positive family history of hypertension. 3. On normal salt intake intra-erythrocyte sodium content was significantly higher in those with a positive family history of hypertension. During high salt intake intra-erythrocyte sodium content decreased significantly in that group and the difference between the hereditary subgroups was no longer significant. 4. In the whole group urinary excretion of noradrenaline, adrenaline and dopamine increased whereas plasma aldosterone decreased during the increased salt intake. 5. Thus, in contrast to some earlier studies performed in young subjects, our results indicate that moderately increased sodium intake acts as a pressor agent in normotensive middle-aged men whether there was a positive family history of hypertension or not. We confirm that men with positive family history of hypertension have an increased intra-erythrocyte sodium content, and that an increase in salt intake seems to increase overall sympathetic activity.

Objective: To determine the relationship between childhood hypertension and family history of hypertension in primary school children in Port Harcourt.Methods: A stratified multi-staged sampling technique was used torecruit pupils between 6-12 years of age, from thirteen primary schoolslocated in three school districts. Data was collected using a pretestedquestionnaire completed by parents / guardians. The average of three blood pressure measurements, weight and height were taken for each pupil, using standardized techniques. Hypertension was defined as average systolic and / or diastolic blood pressure greater than or equalto the 95th percentile for age, gender and height using the standard bloodpressure charts. Family history of hypertension was defined as eitherparent indicating on the submitted questionnaire that they were hypertensive (diagnosed by a physician and/or on antihypertensive drugs)or had a family history of hypertension.Results: A total of 1302 pupils with 717 (55.1%) females and 585(44.9%) males were studied, giving a female to male ratio of 1.2:1. Themean age of pupils studied was 8.82±1.91 years. Sixty one (4.7%)of the pupils examined had hypertension. Of the 1302 pupils, 316(24.3%) had a family history of hypertension. The mean systolic(p<0.001) and diastolic (p=0.220) blood pressures were higher in childrenwith a family history of hypertension than in those without. Ofthe pupils that had a family history of hypertension, 7.9% had  hypertension, while 3.7% of those that did not have a family history, werefound to be hypertensive (p=0.001).Conclusion: A family history of hypertension was associated with a higher prevalence of childhood hypertension than was seen in children without a family history of hypertension.Key words: Childhood Hypertension, Family history.

Family History Of Hypertension

Background: Hypertension is considered as a major health issue in developed as well as developing countries and its possible origin during childhood prompts pediatricians to routinely include measurement of blood pressure (BP) as an integral part of pediatric physical examination. The objectives of the study were to evaluate the normal range of blood pressure in adolescent school going students of 12-16 years, prevalence of hypertension and relationship of BP with variables like age, body mass index (BMI), socioeconomic status and family history of hypertension.Methods: A cross sectional study was undertaken for a period of one year in adolescent school children in age groups between 12-16 years. Detailed clinical examination was done in 1060 adolescent school children and BP was recorded in right upper limb and correlation of BP with BMI, family history of hypertension and diabetes were studied.Results: Mean systolic and diastolic pressure showed linear relationship with age. There was a highly statistically significant difference between mean systolic and diastolic blood pressure between lower and middle socio-economic class. Prevalence of obesity in our study was 1.13%, overweight was 7.83%. Prevalence of hypertension in obese children was 33.33% and in overweight children 18.07%. Family history of hypertension and diabetes carry a significant correlation with elevated systolic and diastolic blood pressure in adolescents.Conclusions: This study revealed that socio economic factors play a significant role in determining the blood pressure of the individual. Children of middle class have significantly elevated mean systolic pressure and mean diastolic pressure than low socio-economic groups.
